This invention relates to a stock feeding device, more particularly adapted vtov feed hogs, and has for its principal object`tlie provision' of a grain feedingV device which will simultaneously grind the grain andbe .operated entirely by the animals'.

Another object of the inventionis to pro-y vide a device which willrequire some energy on the 'part of the hogs in order to obtain 1o their feed,so that they will be kept in a constantly healthy and hungry condition.y

A further object of the invention .is to pro vide a device of this character which canbe placed outv of doors and which will entirely protect the contained grain from rain,

snow, etc. l Y Y A still further object is to provide a hog .feeding device which will prevent the larger vand stronger hogs from crowding the smaller hogsvaway from the feed.

Other objects and advantages reside-in the detail construction of. the improvement, which lis. designed .for simplicity, economy,

Aand eiiiciency. v'lhese'will become more apparent from the following description.

In th'efollowing detailed description of the invention reference is had to the accompanying' drawings which .formV a part. hereof. Lilie numerals refer to like .parts in all views S0 of the drawings and throughout the description.

Fig. 1 is a side elevation and vertical section of my improved hog feeder. the section V being taken on the line 1 1, Fig..2.

Fig. 2 is a horizontalsection of the feeder taken on the line 2 2, Fig. 1.-

Fig. 3 is an enlarged detail view of the supporting standard and itsattachments.

Fig. 4 is a detail view illustrating a protectingfflap with which the feed discharge openings may be provided. n The invention comprises ak feedreservoir 10 arranged to discharge grain through grinding burrs 11 and 12 to a rotary feeding pan 13. The feeding pan 13 is provided with a series of feeding pooketslt from which the hogs receive their feed.

The entire device 1s supported upon a ceno tral standard 15 which is carried in az suitable supporting base 16. The feed reservoir if.

10 rests on, yand is secured to, a supporting .flange 17 which in turn iswelded or otherwise lformed on the lower extremity of a sleevelS surrounding the standard 15. The `upper portion ofthe reservoir 10 is braced from the .sleeve 18 by means of suitable brace bars'r19. rThe sleeve 18, and with it the reservoir 10,

can be raised or lowered upon the standard 16 by means of an adjusting nut20 threaded kon the standard. The nut 20 is provided'with hooked members 21y which engage under;k ,a ange 22 on the upper extremity -of thesleeve 18 so asto support the sleeve and its-attached mechanism.V

The feed reservoir 10 and the sleeve locked from rotation about the standardl by ine-:ans of a pin or bolt 38 which .passes through kthe sleeve 15v and the standard 115.

In the sleeve 18 the bolt 38 passes through f.

slotted openings 39 which allowyvertical `movement of the sleeve. Y

The upper grinding burr 11 is securedrto the' bottom ofthe supporting Hangel'? immediately over the lower grinding burr 12.'

The grain from the reservoir 10 flows to the grinding hurrs 11 and 12 through one yor more discharge openings V22 formed 1in" the bottom of the reservoir-10 and 4through the supporting Harige 17. The How through the suitable valve24.

The lower grinding burr l2 is carried on' a opening 2R can be controlled by meansfofa Ysupporting disc 25 surrounding the standard 15. The supporting' disc 25 is rotatably sun-f of the grinding burrs into the feed pan 13and is forced to the periphery of the Vfeed panv by a series of stationary rake bars 29. The rake bars 29 extend tangentially from pivots 30 on a base ring `31. By securing the rakes 29 upon pivots on the ring 31 they are freeto lie 150 rakes on and follow the plane of the feed pan bottom.

The ring 31 is clamped to the standard 15 immediately above the bottom of the feed pan 5 13 by means of a suitable clamp 40. The

grain iford through openings 32 to each of the f'ed pockets 14 by the action of the rakes 29.

In foperation,-the hogs will force their w snouts into the feed pockets 14 in search of the grain. The pockets all open at a tangent to t e periphery of the feed `pan 10 so that,

in feeding, the hogs will push the pockets forwardly eausing'the'feed pan 13 to revolve. u The rotation of the feed pan under the stationar "takes 29 causes the grain to travel bum 1y in the p'an into the pockets'14. As leffded'pan 13 rotates it will rotate the lower grinding burr 12 against the grinding'surface n ofthe upper grinding burr 11, thus grinding this 'fn flowi from thereservoirl() before its,` eposit' in t e feed pan 13. The upper 'grinding burr is constantly maintained staltdnfary being secured to thestationa'ry 'raser-voirie lThe separationof the grinding burr's`11 and l2an'd the degreeof grinding can be minutely ated' by turning the adjusting nut 20,

y v'hiab will separate or bringfthe grinding Aburrs together, as desired.

l'hereservoird() is'closed by meansof a `weather tight cover 33 secured in placeby 'alfornamental nut 34 upon the upper ex- Y "trema-y bf ale standard 15. 'rile-feed pan 1a j'ggrotected'from the weather by a `conical ld'35"which extends outwardly over the and has a depending 'lip' 36 surrounding e' an.

"'l'ii assist in directing the'grain toward the discharge'openngs 23, a. hopper'37 may, if "desired,'be placedin t'hebottom of the 'reserf'voir'ilO.

"It 'has'been foundby'actual practicey that "the fhgs quickly learn that rotation 'of `the i5 "fed'pnn wifi furnish them with food, so that 'they' M'ewiiling and anxious to operatefthe feeding and grinding mechanism. The hogs "doriot'foliow amy'certain pocket around the I"devicebutsoon learn to'pushone poeketaway .9 A'f'lom'trem and start feeding on ithe next folbwingpotket Th'ey will be found to stand iin abrcle *about the device pushing i the pocketsfrom 'oneto anotheras they feed. As dthe pockets-approach theunext hog they will befilledbypassinfr one of the rakes'QQ. C*

reventa the larger hogs from crowding "the smaller ones away, since they do not leave the .positions at whichthey started to feed.

All number of the openings Q3 and Vthe may-be employed as desired, depending upon the number of hogs being fed. The ter the'number of rakes the more rapid l will be the fillinor of the pockets.

'I'nusin'` this device the reservoir 10 can Abe "555" llecl wit ungt'ound` grain sufficient to: last vice 14, iaps 41 may be provided hinged at 42 -'f above the openings 32 as shown in Fig. 4, so that'the grain'can be forced outwardly into `the pockets, but snow and rain can not be blowninward into the pan.

i While aspecific form of tbe improvement i has been described and illustrated herein, it is desired tobeunderstood that the same may be varied, within the scope of the appended elaims,`without departingffrom the spirit of the invention.
